About this study

Official title: Effects of Mirror Therapy Combined With Contralaterally Controlled Functional Electrical Stimulation on Functional Recovery and Neuroplasticity in Patients With Peripheral Nerve Injury

The goal of this trial is to evaluate the effects of mirror therapy combined with contralaterally controlled functional electrical stimulation on motor recovery and neuroplasticity in patients with peripheral nerve injury. The main questions it aims to answer are Question 1: To compare corticomuscular coherence between the groups of mirror therapy combined with contralaterally controlled functional electrical stimulation, sham mirror therapy combined with contralaterally controlled functional electrical stimulation, and control group.

Question 2: To compare sensorimotor recovery between the groups of mirror therapy combined with contralaterally controlled functional electrical stimulation, sham mirror therapy combined with contralaterally controlled functional electrical stimulation, and control group.

Question 3: To evaluate the effects of each intervention on corticomuscular coherence and sensorimotor recovery 12 weeks post-intervention.

Participants will be asked to exercise their affected hand together with the unaffected hand while receiving contralaterally controlled electrical stimulation in front of the mirror or sham mirror. Researchers will compare the effects of mirror therapy combined with contralaterally controlled functional electrical stimulation on corticomuscular coherence and sensorimotor recovery with the other groups.

The goal of this trial is to evaluate the effects of mirror therapy combined with contralaterally controlled functional electrical stimulation on motor recovery and neuroplasticity in patients with peripheral nerve injury. The main questions it aims to answer are:

Question 1: To compare corticomuscular coherence between the groups of mirror therapy combined with contralaterally controlled functional electrical stimulation, sham mirror therapy combined with contralaterally controlled functional electrical stimulation, and control group.

Question 2: To compare sensorimotor recovery between the groups of mirror therapy combined with contralaterally controlled functional electrical stimulation, sham mirror therapy combined with contralaterally controlled functional electrical stimulation, and control group.

Question 3: To evaluate the effects of each intervention on corticomuscular coherence and sensorimotor recovery 12 weeks post-intervention.

Eligible participants will be randomized into three groups:

MT and CCFES group: mirror therapy combined with contralaterally controlled functional electrical stimulation Sham MT and CCFES group: Sham mirror therapy combined with contralaterally controlled functional electrical stimulation Control group: conventional physiotherapy.

Each participant will receive conventional physiotherapy for 50 minutes daily, twice a week for 12 weeks. Conventional physiotherapy includes scar management, joint range of motion exercise, strengthening, stretching, and functional training. Participants in the MT and CCFES group or Sham MT and CCFES group will receive 30 minutes daily, twice a week of the intervention for 12 weeks in addition to the conventional physiotherapy. In the MT and CCFES group, the participants will sit in front of the mirror and watch the mirror reflection of the unaffected hands. At the same time, contralaterally controlled electrical stimulation will be conducted to make the affected hands move with the unaffected hands. The participants in the Sham MT and CCFES group will sit in front of the mirror without mirror reflection, but doing the exercise with contralaterally controlled functional electrical stimulation. All participants will receive the evaluations at baseline and 12 weeks after the intervention. The evaluations include:

Electroencephalography of α and β bands from the sensorimotor cortices will be recorded.

Electromyography will be performed during maximum isometric pinch or lateral pinch strength measurements.

Maximum isometric grip strength, tip pinch strength, lateral pinch strength, sensation tests, and upper extremity function will be measured.

Questions about this trial

What is this clinical trial studying?

A study testing mirror therapy and conventional physiotherapy in people with Peripheral Nerve Injury, run by National Taiwan University Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

change from baseline in corticomuscular coherence at week 12 (time frame: baseline, week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06209632, which also lists 14 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jan 2026.
